Source for young coconut meat?

[Susan]

Just received a new cookbook from Costa Rica and plan to work my way through it a recipe at a time. Some I will have to save for our Hilo visit in October to take advantage of the fruits I cannot find here.
Quite a few of the recipes call for young coconut meat. Do you know if I would be able to find this at Makuu or the Hilo Farmers markets?
